People are talking about ACID, which comes with SQLite for certain, but here's the biggest thing: all that regular data, which has specific relationships to each other, is available in a well understood, battle tested high level language. Not Perl, not Python, not Tcl, but SQL. Some people criticize fossil as unsuitable for the task of managing all the subtle relationships and being able to deftly handle lots of data, because it's written in C. They're missing the forest for the trees. SQL does the heavy lifting here.

Speaking of Tcl, the author of Sqlite and Fossil is also on the Tcl core team.
